Abstract (en)

A combustion system for an engine, such as a gas turbine engine is provided. The combustion system has a ceramic component (24), such as ceramic combustor liner, and at least one metal support component such as a metal ring (220), for providing radial and axial support to the ceramic component. The at least one metal support component (20) includes a structure, for minimizing stress and for increasing compliance of the metal support component (20) with respect to the ceramic component (24). The structure comprises an outer spring element (90) positioned between said metal ring (220) and an inner surface (92) of the ceramic combustor liner (24), an inner spring element (94) positioned adjacent an outer surface of the ceramic combustor liner, and a clamping ring (102) positioned outward of the inner spring element (90). Each of the spring elements (90,94) and the clamping ring (102) have a plurality of openings (98,100,104) which align with openings (38) in said ceramic combustor liner (24). Means (40) pass through the aligned openings to join said clamping ring (102) and said spring elements (90,94) to said ceramic combustor liner (24).
